Boston police said they received a call about 8:30 p.m. reporting a robbery at Wells Liquor Store in the 1700 block of Dorchester Avenue.

Store employees told officers an African-American male about 5 feet 9 inches tall, wearing glasses and dark clothes walked into the store and demanded money, telling them he had a firearm. Police said the employees gave the man an undisclosed amount of money, but a fight broke out when two employees fought back.

Police said the fight spilled out to the sidewalk and ended when the man, who was struck several times, escaped toward Lonsdale Street.

Several hours later, police said they received a call to check on a man who appeared to be injured in the area of Florida and Mallet streets. Responding police said they found the man, later identified as Sean Brown, 38, suffering from what appeared to be lacerations and bruises to his head.

Police said Brown was taken to the Boston Medical Center for treatment.

Police said Brown was arrested on armed robbery charges after detectives recognized him as the same individual wanted in connection with the liquor store robbery.
